## Utangulizi
2022-12-24 19:19:02 +00:00
iButton ni jina la kawaida la ufunguo wa utambulisho wa elektroniki uliowekwa katika **chombo cha metali chenye umbo la sarafu**. Pia huitwa **Dallas Touch** Memory au kumbukumbu ya mawasiliano. Ingawa mara nyingi huitwa kimakosa kama ufunguo "wenye sumaku," hakuna **sumaku** ndani yake. Kwa kweli, kuna **chipu kamili** inayofanya kazi kwa itifaki ya dijiti iliyofichwa ndani yake.

### Ni nini iButton? <a href="#what-is-ibutton" id="what-is-ibutton"></a>
2022-12-24 19:19:02 +00:00
Kawaida, iButton inamaanisha umbo la kimwili la ufunguo na msomaji - sarafu ya mviringo yenye mawasiliano mawili. Kwa fremu inayomzunguka, kuna mabadiliko mengi kutoka kwa kizuizi cha plastiki cha kawaida chenye shimo hadi pete, vipendanti, n.k.

Ufunguo unapofika kwa msomaji, **mawasiliano hukutana** na ufunguo hupata nguvu ya **kuhamisha** kitambulisho chake. Mara nyingine ufunguo **hausomwi** mara moja kwa sababu **PSD ya mawasiliano ya intercom ni kubwa** kuliko inavyopaswa kuwa. Kwa hivyo, mipaka ya nje ya ufunguo na msomaji haziwezi kugusana. Ikiwa ndivyo, utalazimika kubonyeza ufunguo juu ya moja ya kuta za msomaji.

### **Itifaki ya 1-Wire** <a href="#id-1-wire-protocol" id="id-1-wire-protocol"></a>
2022-12-24 19:34:46 +00:00
Vifunguo vya Dallas hubadilishana data kwa kutumia itifaki ya 1-wire. Kwa mawasiliano ya data (!!) kwa pande zote mbili, kutoka kwa bwana kwenda kwa mtumwa na kinyume chake. Itifaki ya 1-wire hufanya kazi kulingana na mfano wa Bwana-Mtumwa. Katika mtandao huu, Bwana daima huanzisha mawasiliano na Mtumwa anafuata maagizo yake.
2022-12-24 19:34:46 +00:00
Ufunguo (Mtumwa) unapowasiliana na intercom (Bwana), chipu ndani ya ufunguo huzimwa, ikipewa nguvu na intercom, na ufunguo huwekwa tayari. Baada ya hapo intercom inaomba kitambulisho cha ufunguo. Kisha tutachunguza mchakato huu kwa undani zaidi.

Flipper inaweza kufanya kazi kama Bwana na Mtumwa. Katika hali ya kusoma ufunguo, Flipper hufanya kazi kama msomaji yaani inafanya kazi kama Bwana. Na katika hali ya kujifanya ufunguo, flipper inajifanya kuwa ufunguo, iko katika hali ya Mtumwa.
